PASS A+ [2026]
• Which chamber of the heart pumps oxygenated blood into the systemic circulation?
• A. Right atrium
• B. Right ventricle
• C. Left atrium
• D. Left ventricle
Answer: D — The left ventricle pumps oxygenated blood through the aorta to the body.
• What is the primary function of the atrioventricular (AV) node in cardiac conduction?
• A. Initiate electrical impulse for each heartbeat
• B. Delay conduction to allow for atrial contraction before ventricular contraction
• C. Trigger ventricular contraction directly
• D. Send impulses to SA node for pacing
Answer: B — AV node slows conduction to allow ventricles to fill after atrial
contraction.
• What is the normal paper speed for a standard EKG tracing?
• A. 10 mm/sec
• B. 25 mm/sec
• C. 50 mm/sec
• D. 100 mm/sec
Answer: B — Standard EKG recorders operate at 25 mm/sec.
• On a 12-lead EKG, which lead typically shows the “classic” upright P wave in normal sinus
rhythm?
• A. Lead I
• B. Lead II
• C. Lead aVR
• D. Lead V1
Answer: B — Lead II often shows the best view of the atrial depolarization (P wave).
• You count 6 QRS complexes in a 6-second EKG strip. What is the approximate heart rate?
• A. 60 bpm
• B. 90 bpm
• C. 100 bpm
2026 Graded A+ EXAM
, • D. 120 bpm
Answer: C — 6 complexes/6 sec × 10 = 60/min? Actually that equals 60. Wait: formula:
number of QRS in 6 sec × 10 = rate → 6 × 10 = 60 bpm. So correct: A.
• A patient’s EKG shows regular rhythm, heart rate 55 bpm, P waves before each QRS, and
normal PR/QRS intervals. What is this likely rhythm?
• A. Sinus bradycardia
• B. Atrial fibrillation
• C. Ventricular tachycardia
• D. First-degree AV block
Answer: A — Regular rhythm, P before each QRS, rate < 60 → sinus bradycardia.
• What does a prolonged PR interval (> 0.20 seconds) on EKG suggest?
• A. First-degree AV block
• B. Bundle branch block
• C. Ventricular hypertrophy
• D. Atrial fibrillation
Answer: A — Prolonged PR indicates delayed AV conduction (1º AV block).
• What part of the heart’s conduction system is considered the “pacemaker” under normal
conditions?
• A. AV node
• B. Bundle of His
• C. Sinoatrial (SA) node
• D. Purkinje fibers
Answer: C — SA node initiates the impulse.
• Which of these is the correct sequence of cardiac electrical conduction in a normal heart?
• A. SA node → AV node → Bundle of His → Purkinje fibers → atria → ventricles
• B. SA node → atria → AV node → Bundle of His → Purkinje fibers → ventricles
• C. AV node → SA node → atria → ventricles → Purkinje fibers
• D. Atria → SA node → AV node → ventricles → Purkinje fibers
Answer: B — SA node → atrial depolarization → AV node → Bundle of His →
Purkinje → ventricular depolarization.
• Which wave on an EKG represents ventricular depolarization?
• A. P wave
• B. QRS complex
• C. T wave
• D. U wave
Answer: B — The QRS complex corresponds to ventricular depolarization.
